Investment Insights

Based on property information with market context.

This expansive legacy property in Putnam County encompasses over 320 acres, presenting a unique opportunity for development. The former summer camp includes eight separate tax lots, with nearly 50 acres zoned for commercial use across three parcels and approximately 270 acres zoned for residential use across the remaining five. The 95.63-acre flagship parcel, accessible from Ballyhack Road, features a 20-acre private lake with an updated dam and semi-developed waterfront. Miles of established trails traverse the property, revealing original camp structures in varying states of disrepair, including a lakefront lodge, dining halls, recreation and education buildings, dormitories, a medical facility, and an inground pool. A new, state-of-the-art sewage treatment plant, capable of servicing 60-65 homes and complete with a current SPDES permit, full generator, and redundant backup system, is located on site. An additional entrance from Old Route 22 can be reclaimed via one of the commercial parcels. The land includes two tributaries of the East Branch Croton River and approximately 1,640 feet of direct frontage on the river. A 3-bedroom ranch home at the Ballyhack entrance can serve as a caretaker's residence. The property's multi-zoned, multiple-parcel status allows for a variety of permitted uses in C1 zoning, such as research and development, veterinary hospitals, greenhouses and nurseries, restaurants, health or fitness clubs, recreational sports facilities, business and professional offices, banks, and drive-in and fast food establishments. Special uses include light manufacturing, retail centers, warehouses, conference and cultural centers, membership clubs, nursery schools, and day care centers.
